Justin Bieber treated fans to a never-before-heard song during a recent Purpose show.
Bieber kicked off his new world tour last week to promote his latest album Purpose, which sits at No. 5 on the Billboard 200 this week, but he's already adding fresh music to the setlist. Fans at Bieber's Portland, Oregon show on Sunday witnessed the Biebs perform a new song reportedly titled "Insecurities." After cranking out a number of choreographed routines, the "Company" singer caught his breath by singing the new acoustic song under a spotlight. "I'm the one you wake up thinking about," Bieber sings, promising he could take away all their insecurities if given the chance. Watch Bieber serenade 20,000 fans below:
